Answer 2

Conduction

1. In conduction, heat transfer takes place between objects by direct contact.
2. The heat transfer takes place due to the difference in temperature.
3. The heat transfer in conduction is slow
4. The heat transfer occurs through a heated solid object.
5. It does not follow the law of reflection and refraction.

Convection

1. In convection, the heat transfer takes within the fluid.
2. The heat transfer occurs due to the difference in density.
3. The heat transfer in convection is faster.
4. The heat transfer occurs through intermediate objects. For example, heat transfer between air and water.It does not follow the law of reflection and refraction.

Radiation

1. In radiation, heat transfer occurs through electromagnetic waves without involving particles.
2. The heat transfer occurs in all objects with a temperature greater than 0 K.
3. The heat transfer in radiation is the fastest.
4. The heat transfer occurs through electromagnetic waves.
5. It follows the law of reflection and refraction.
